⚙️ Fit Notes

• This drive is M.2 SATA (AHCI), not NVMe. Your system’s M.2 slot must support SATA-based M.2 SSDs; some newer systems provide NVMe-only M.2 slots that are not compatible.
• Form factor is M.2 2280 (22 x 80 mm). If your system only accepts shorter lengths (2242/2260) or uses a proprietary carrier, confirm mechanical fitment.
• When replacing an existing 256GB M.2 SATA SSD, you can generally use any of the interchangeable part numbers listed as long as your system supports generic M.2 SATA storage and is not locked to a specific OEM firmware.
• Always back up data before swapping drives and check whether you’ll be cloning the existing OS or performing a fresh installation.
• For desktops and workstations, confirm whether the M.2 slot shares bandwidth with other SATA ports; some motherboards disable a SATA port when an M.2 SATA device is installed.
